My sister was giving me a massage, very sensual & afterwards she said she needed to take a shower to freshen up. I couldn't help wondering if she'd been turned on by me & when I went downstairs to losd a wash I noticed this pair of panties on top of the pile, still warm. I naughtily peeked inside them & baby, were they slimy & wet, the cunt scent absolutely amazing! My cock was like rock & I smeared all the delicious juices & secretions all over it. Boy, I had to come, so I beat the meat with a vengeance & shot the most incredible amount of load right into those sweet panties & yes, they needed a thoroughly good wash after I was done!
